CONFERENCE SERIES||Volume:||Applications of Novel Scintillators for Research and Industry 2016 (ANSRI 2016)||Number:||763||Issue:||1||First Page:||012009||Abstract:||Consolidated techniques used for space-borne X-ray and gamma-ray instruments are based on the use of scintillators coupled to Silicon photo-detectors. This technology associated with modern very low noise read-out electronics allows the design of innovative architectures able to reduce drastically the system complexity and power consumption, also with a moderate-to-high number of channels. These detector architectures can be exploited in the design of space instrumentation for gamma-spectroscopy with the benefit of possible smart background rejection strategies. We describe a detector prototype with 3D imaging capabilities to be employed in future gamma-ray and particle space missions in the 0.002-100 MeV energy range. The instrument is based on a stack of scintillating bars read out by Silicon Drift Detectors (SDDs) at both ends. The spatial segmentation and the crystal double-side readout allow a 3D position reconstruction with ∼3 mm accuracy within the full active volume, using a 2D readout along the two external faces of the detector. Furthermore, one of the side of SDDs can be used simultaneously to detect X-rays in the 2-30 keV energy range. The characteristics of this instrument make it suitable in next generation gamma-ray and particle space missions for Earth or outer space observations, and it will be briefly illustrated.||Conference Name:||Applications of Novel Scintillators for Research and Industry 2016 (ANSRI 2016)||Conference Place:||Dublin, Ireland||Conference Date:||11-13 May, 2016||URI:||http://hdl.handle.net/20.500.12386/24303||URL:||https://iopscience.iop.org/article/10.1088/1742-6596/763/1/012009||ISSN:||1742-6588||DOI:||10.1088/1742-6596/763/1/012009||Bibcode ADS:||2016JPhCS.763a2009F||Fulltext:||open|
